It takes roughly about 3 drops of calcium chloride added to a sodium sulphate solution to form a precipitate of CaSO4 whereas, it takes one drop of calcium chloride added to a sodium sulphate solution which was already mixed with 8 drops of sulphuric acid to form a precipitate. Why does the number of drops of CaCl2 differ between the two?
